| Abstract(in English) | Sodium secondary batteries are expected as one of the post lithium ion batteries (LIB) because they have a higher energy density and lower cost compared to LIB. In this study, we focused on a Cu-based oxide as an electrode material of the sodium secondary batteries. We synthesized a Cu-based oxide, NaCuO2, and its electrochemical properties were investigated as the positive electrode for sodium secondary batteries. As a result, the sodium secondary batteries with NaCuO2 positive electrode showed the first discharge capacity of 150 mAh/g at a current density of 0.5 mA/cm2 Structural change analysis of NaCuO2 suggested that NaCuO2 converted to amorphous state during the first discharge process, and the amorphous NaCuO2 worked as the positive electrode. |
